Ocata Series Release Notes¶

15.1.16¶

The gnocchi_keystone_auth_plugin variable has been deprecated. gnocchi_keystone_auth_type should be used instead to configure authentication type.

The os_gnocchi role now includes a facility where you can place your own default api-paste.ini or policy.json file in /etc/openstack_deploy/gnocchi (by default) and it will be deployed to the target host after being interpreted by the template engine.

New variables have been added to allow a deployer to customize a gnocchi systemd unit file to their liking.

The task dropping the gnocchi systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

For the os_gnocchi role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the gnocchi_*_init_config_overrides variables which use the config_template task to change template defaults.

Specify the gnocchi_auth_mode var to set the auth_mode for gnocchi. This defaults to basic which has changed from noauth to match upstream. If gnocchi_keystone_auth is true or yes this value will default to keystone.

Specify the gnocchi_git_config_lookup_location value to specify the git repository where the gnocchi config files can be retrieved. The api-paste.ini and policy.json files are now retrieved from the specified git repository and are not carried in the os_gnocchi role.

The gnocchi_archive_policies and gnocchi_archive_policy_rules variables never had full support in the role so were ineffective at the intended purpose. The task references to them have been removed and the library to perform gnocchi operations has also been removed. This eliminates the need for the gnocchi client to be installed outside the virtual environment as well.

The variables gnocchi_requirements_git_repo and gnocchi_requirements_git_install_branch have been removed in favour of using the URL/path to the upper-constraints file using the variable pip_install_upper_constraints instead.

The variable gnocchi_required_pip_packages was incorrectly named and has been renamed to gnocchi_requires_pip_packages to match the standard across all roles.

The gnocchi_keystone_auth is deprecated, and will be removed in the Queen cycle. Setting gnocchi_auth_mode to keystone will achieve the same result.
